Nice! I've totally forgotten about using the DOS Version in DOSBOX!
Still, one plus for runtos: long filenames as well as no startup time :)
I don't know how fast DOSBOX' dynarec is compared to the static Musashi interpreter,
but on my CoreI7 System assembling NoCrews MP2 Replayer takes 0.0749s compared to 0.0391 via Wine (already started once), so fast enough for me :)
Assembling it on a PI3 needs 4.9seconds though; and on a PI1 i have 14.479s compared to 14.020s on a Falcon060@66Mhz...
The original plan was to disassemble either the Windows Exe or the Atari PRG and convert that one to some kind of C as was done before (i.e. opendune) but that's too much work for me right now.
